pivot, fastened to the standard H by a screw m and having in its front an opening or window m', `Fig. 5, behind which a pla-te ot glass is intcrpose between said front of the casing and the be ring-bloek l. Since the ivot res'ts in the groove of the said bloc as shown in'Fig. l, the end of said pivot is neeessarily in contact with said glass plate. The two glass plates minimize friction at the ends of the pivots, 'while reventing any lateral movement of the tarewam and attachments, and thus preventing the contact of said beam with either standard Il. The pivot is not shown in Fig. 5, as it would hide a part ofthe bearing-block and shell and does not seem needed in said View.

The computingpanel G has the same graduation on both faces, these faces being counterparts in all respects, so that the customer may observe the figures indicated at the same time with the seller, though having the panel between them.

N dcsipnates a pair of counterpart segmentshaped p ates which to ether constitute a sliding attaching-bracket igor a pair of pivoted indexes O (Y, one of said plates and one of said indexes being located on each side of the panel.

Each plate N is provided with lugs n, overla ping longitudinal guideways l on the si es of the said panel G, constituting a frame or border for the longitudinal slot G of said channel, and screws Q li are )assed through said plates and slot, holding tlie two -plates in position against the said panel, though not so tightly as to interfere with slipping them along the slot and guideways from point to point. The. scre'w Q is of eater length and size than screw R, adaptmg it tobe passed through the two indexes and to serve as a bearing therefor. Each index has a light plate 0Z attached to and movingwh it, the curved outer edge of each plate lHitting against a shoulder P2, raised den its bracket-plate l? or P, the curvature of said edge and shoulderY being circular and concentric with a curved series of graduations carried by said bracket-plate, these being preferably on a detachable card. l The index O, normally toward the scale-platform, is

more inished than the other one and bent near the tip to engage a segmental series of notches N2., also concentric with the said graduations. Index O is rovided at its rear end with a weighted han le S, serving, with the said plates and indexes, as an additional sliding poise which may be moved to indicate the weight of the material after the poise D aforesaid has been shifted to indicate that of Ypreferably double, consistin the pan or containing vessel. fguchlndication is made b a pair of ointer T, presented upward an do'wnwar from a prolectmg art of the other end of the bracketplate.

eyond screw R. These pointers trayel over a pair of straight series of graduations arranged, respectively, above and below the slotand guideways aforesaid.v The upper series is with blan spaces between, except that the space for the I'irst pound is divided for quarters thereof, with suitable fractional numerals. The lower serles has each pound-space divided for opnces avoirdupois. .Of course any other measures of gravity may be subfl stituted.

index O is made in two sections, joined near the middle by a screw S', the rearward seetionfwhich has weight S appended there: to, being the heavier and provided with a raised integral, hub S?, surrounding the screw Q, The light forward section of this index has a raised lin or thumb-piece to facilitate the turning of the indexes by hand'. The other index 0 carries no weight, has no enlarged section, raised hub, or. thuml piece, and engages no notches,'but occupies the same osition, moves with the other index, and oi course points to the same numbers at the same time,

T he series oi-graduations for each plateare of red and black numbers arranged a ternately, as shown, in two rows of parallel curvature. In shifting the index .O from notch to notch it ,graduated for pounds, as shoun,1

ioc-A passes also from figure to figure of said scale,

this double arrangement making possible the use ofvmore numbers'than would oth'eiwisel 4each set beiinr concentric with that on the movable bracle't-plate and the intervening spaces occupied by concentric series oi subdi-Z vision-indicating marks, also-alternating, lthe red being above each line, the latter below, or vice versa. These curved series of numbers and graduations on the panel indicate price vand' are primarily intended for dollars and cents, but may be used for any other moneta denominationsfor example, francs an centimes. 1 The indexes are prolonged over and beyond the front of the bracketplates to indicate numbers on these price series at the same time that they indicate numbers on the similar series of the bracketplates which stand for the price per pound.

The cards othese` latter series are set into curved depressions of the faces of said bracket-plates below the curved shoulders aforesaidand raised curved `flanges or lwalls N3 on the forward edges of the brackets, in'

one of which walls the notches N2, already mentioned, are formed. `Also each shoulder eene@ has it eurvedzli` ,bl bent in e. laine at ri ht angles toit and extended oiwverd over the number-card to hold it in place. @i course these and other' structural details may be greatly varied with/out affecting the niein ieetures ot our invention.

In opera-tion the zgoods are tiret weighed, es above stated. if then the pointer T indicates 2 on the straight seriee oi greduations as the number of pounds and the price is eight cents a pound, the index ie turned over 8 on the oord of vthe plete, the series of which indicates the price per pound, the index at the saine time engaging one of the notches for provenringelr any accidentel ehanve of place. The point of said index will t ien be just over the number lo in red on one of the Curved totalprice series oi the panel and just ebow the straight horizontal dividing-line, The rule is that the rrd num bers und graduetions shall be counted when the index-points just above the seid dividing; line and over the red graduetione oi the niain chart and the number under the index the prioe-per-pound series oi2 the braol-ret-plate bored. This .being true of the 3 in the latter series, weget the resul"U sixteen. Conversely, a blaolr nuinber el the 'price-pen pound series on the brnolret when under the index calls for the point ot' the index to register slightly below the aforesaid horizontal div iding-linealv drovvcr the bleek subdivision rreduations .nd indicating that the blank ligures of the total-price series oi the main foliart are to be counted. It then we suppose the price per pound to be seven cents instead of eight and shift the index onoordingly, we get the oorreet result, fourteen.

The saine rule applies to reading the (,fraduni tions between the series, red being above the line, bla-ok below. if the weight be between two numbers for pounds7 the point of the index alter turning it over the price per pound will be on the proper line between two curved series of the ooinputingpanel, and the read ing will be as before, except that no numerals are atlixed to these graduations, and they must be counted or estimated by length, each short one representing one cent and every fifth one standing at twice the length of the others, so it'is readil;T distinguished and represents iive cents. iu red and blaokbetween the dil lerent pound ligures ilron; l to l0H above and below 'the horizontal lines of the main chart are subdivided into a nuinber of parte equivalent to the price in Gents per pound and ere the saine in :ill the pound-spaces along the suine horizr ntal line. To illustrate, suppose we use the black figures below one oi' the horizontal lines and the price is ten cents per pound. Each pound-division in that lino from H i l to 10 iss-subdivided by nine dashes, each dash representing one cent, Yli" we use there-d ligures above the line and the price` is twelve These dash graduations y eents 4per pound, the stuur pound subdivisions above the line aro llvn dividen by eleven dashes, eaoh representing one nent, the i'inul pound-mark ol' oourse representing the lest dash or they tenth und iurlhh rent, respectively.
